AMD Error 184 is saying that you are trying to install a AMD Driver on a Operating System that it isn't compatible with.
Make sure your Windows is fully updated via Windows Update for AMD Drivers to install and work correctly.
Here is the latest AMD VEGA56 Driver from 12/2021 for both Windows 10 & 11: https://www.amd.com/en/support/graphics/radeon-rx-vega-series/radeon-rx-vega-series/radeon-rx-vega-5...
Make sure you use DDU (Display Driver Uninstaller) with the internet disconnected and deleting the previous AMD Installation folder at C:\AMD.
Download the full Vega56 package and now see if it installs and recognizes your GPU card. If you are using a unsupported Windows OS version that probably is the reason for that error.
